PROCESS OF TREATINGIHIDES.

To all whom it may concern:

Be it known that I, FRANK R. VVEssA, a citizen of the United States, residing at N orwood, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Processes of Treating Hides, of which the following is a specification.

My invention relates to improvements in process of treating hides in the production of enameled leather.

One of its objects is to provide a process of treatment which will require less space for the treatment of a given quantity of hides.

Another object is to provide a process requiring less labor.

Another object is to provide a process requiring less apparatus and permit the employment of more substantial and perma nent apparatus.

Another object is to so arrange the hides in the baking steps as to attain a superior article and also to reduce the oven cap acity ref quired.

It further consists in certain details, all of which will be more fully set forth in the description of said process and the aecompanying drawings, in which,

Figure 1 is a view of a frame with hide attached, as employed in my improved process` Fig. 2 is a perspective view of a hide ready to be introduced into the oven as shown in Fig. 3. Fig. 3 is a section through an oven showing the hides arranged therein. Fig. i is a detail view of one of the clamps mployed to attach the hides to the frame iig. 1.

By my improved process of treatment, frames, D, preferably of metal are permanently located at the points where the hides are to be coated with enamel and stoned. These frames may be set upon their own legs, D', which may be screwed to the floor, if desired. Then by employing metal clips, K such as shown in Fig. 4, for instance, which can be quickly attached to the hides and buttons, knobs, H or similar means for automatically grasping or locking the cords I leading such clips to the frame, after being strained, I am enabled to attach to and detach the hides from the frames more quickly and readily than it has heretofore been possible to transfer the hides and their' wooden frames from place to place.

In removing a hide from one of my perma- Specification of Letters Patent.

nent frames, a pole, or rod, E, is placed beneath the hide and after the clips are released, the hide hangs over the pole, as shown in Fig. 3, and may be thus carried to the baking oven or to another frame for treatment.

In the baking of the hides, the poles are placed side by side upon guides, d, in the ovens, F, and I am enabled thus to place many more hides in an oven ol a given size than could be done where the wooden frames were placed in the ovens vwith the hides attached, thus requiring less oven space. Also, the hides are in better position to attain the desired result, as should there be any tendency of the enamel to flow, it will flow evenly toward the edges of the hide,

leaving an even coat over the whole surface,4

while with hides on the frame, there are pockets, or baggy places toward the center of the hides, and the edges are always higher. Thus any iiow would accumulate in these pockets and would be baked at these places into a thicker coat than desired. Also, with the hides suspended on the poles, there is a better circulation in the ovenand all parts are evenly and thoroughly baked. As the hides are strained again after each baking step, they can be evenly and tightly drawn upon the frames, and the stoning and reco ating can be more effeetually done and a better result attained than by the use of a single frame throughout, as with the single frame pockets occur which cannot be readily taken out, and which are objectionable in the subsequent baking, stoning and recoating Steps.

Having described my process, what I claim is:

1. The process of treating hides comprising the following steps, attaching the hides to frames and applying a coat of enamel, detachin T the hides and suspending them in a vertiei position in an oven to bake the enamel, removing the hides from the oven attaching them to frames and stoning and re-coating them, then removing them from the frames and suspending them as before in an oven to be baked.

2. The process of treating hides which comprises the use of a series of permanently located frames and consists of the following steps, straining the hides upon the Jfirst series of frames and applying a filler coat, detaching the hides from said frames and suspending them side by side upon horizontal bars in an oven and baking said coat thereon, removing said hides and straining removing saidfhideszand straining them upon them upon a second series of frames, stoning the hides and then re-ooating `them YWhileso strained upon the frames, vdetahing the' hides from said second series .of frames/and,y suspending them side by side upon horizontal bars in an oven, and baking the last mentioned coat.
